Fix an unexpected calendar or event time
Check the event start and end dates, the event timezone and the calendar display timezone.
Compare the settings
Check the event start and end dates, the event timezone and the calendar display timezone. For multi day events, confirm the selected cue or check-in day. For an overnight cue, review the end-day setting.
Check external calendars
An exported ICS file reflects the data at export time. Compare a fresh export after a schedule change and review the receiving calendar’s timezone. Avoid repeatedly importing old files, which can produce confusing copies.
If it continues
Contact support with the expected time, displayed time, timezone names and affected view. Do not change the real event date solely to compensate for a display difference.
